[Exim] forward mail

    I have two exim servers, one (10.10.106.250) mail.my.domain.com, it's my

main server where wall mail arrives.
    Now i have a second server in a different location, (10.10.107.250)
mail2.my.domain.com, where i will be putting new users.

    How can i forward all mail for non existing user in mail.my.domain.com to
mail2.my.domain.com ???(example!!!)

    How can i send messages directly to domain.com instead of sending them
through mail.my.domain.com ???
